HIFI OP-AMP Amplifier NE5532 Preamplifier Volume Tone Control assembled Board

1、Power supply circuit adopts full bridge rectifier

2、Effectively eliminate the high frequency interference of AC power grid

3、Chip has high conversion rate and strong drive ability

4、Better performance,noise is very small

5、Sound warm and distorted, high fidelity

Description:

High quality filter power supply. The four pins of rectifier respectively in parallel

connect with decoupling capacitor, which can effectively eliminate the

high frequency interference of AC power grid. Now the clutter interference of

power grid is very small and the voltage is quite stable. So the item

has better performance.The

chip has high conversion rate and strong drive ability. The frequency

band is wide and noise is very small.
